人们对人格病理学的日常稳定性和波动性知之甚少。为了解决这一知识上的差距，我们在100天的时间里调查了人格病理学的自然表现。一组被诊断为任何人格障碍（PD）的个体（N=101）完成了连续100天（Mdn = 94天，范围= 33-101天）的每日日记研究。参与者每天完成30种人格病理表现的评分。研究人员随后检查了研究过程中的稳定性和可变性模式。结果表明，个体PD表现和PD表现的领域在不同的日子里是不同的，并且在频率上差异很大。此外，PD结构域的个体平均值和变异性水平在几个月内高度稳定，PD结构域的个体平均值可以通过PD特征的基线性格评分来预测，具有高度特异性，PD结构域的每日变异性与PD特征水平升高有关。这种发现模式表明，症状加剧和减轻的动态过程在平均水平上是稳定的，随着时间的推移，其表达是变化的，这是人格病理学的特征。此外，性格评分是PD特征平均每日表达的重要预测因子。人格障碍的一般定义包括描述其表达的相对稳定性（例如，“持久的”、“普遍的”、“不灵活的”）。这项自然主义的日常日记研究表明，人格障碍实际上是其表达的稳定性和可变性的结合。
Very little is known about the daily stability and fluctuation of personality pathology. To address this gap in knowledge, we investigated the naturalistic manifestation of personality pathology over the course of 100 days. A group of individuals (N=101) diagnosed with any personality disorder (PD) completed a daily diary study over 100 consecutive days (Mdn = 94 days, Range = 33–101 days). Participants completed daily ratings of 30 manifestations of personality pathology. Patterns of stability and variability over the course of the study were then examined. Results indicated that individual PD manifestations and domains of PD manifestations were variable across days and differed widely in their frequency. Additionally, individual averages and level of variability in PD domains were highly stable across months, individual averages of PD domains were predicted by baseline dispositional ratings of PD traits with a high degree of specificity, and daily variability PD domains was associated with elevated levels of PD traits. This pattern of findings suggests that dynamic processes of symptom exacerbation and diminution that are stable in mean level and variability in expression over time characterizes personality pathology. Further, dispositional ratings are significant predictors of average daily expression of PD features. The general definition of personality disorders includes descriptors of the relative stability in their expression (e.g., “enduring,” “pervasive,” “inflexible”). This naturalistic daily diary study shows that personality disorders are, in fact, a combination of stability and variability in their expression.
